Delepinoceratidae
Delepinoceratidae is one of three families in the Goniatitoidea superfamily. They are an extinct group of ammonoid, which are shelled cephalopods related to squids, belemnites, octopuses, and cuttlefish, and more distantly to the nautiloid Nautiloids are a group of marine cephalopods ( Mollusca) which originated in the Late Cambrian and are represented today by the living ''Nautilus'' and ''Allonautilus''. Fossil nautiloids are diverse and speciose, with over 2,500 recorded species ...s. References The Paleobiology Databaseaccessed on 10/01/07 Goniatitida families Goniatitoidea {{Goniatitida-stub ...

Goniatitidae
Goniatitidae is one of three families included in the ammonoid cephalopod superfamily Goniatitoidea, known from the Lower Mississippian to the Upper Permian The Permian ( ) is a geologic period and stratigraphic system which spans 47 million years from the end of the Carboniferous Period million years ago (Mya), to the beginning of the Triassic Period 251.9 Mya. It is the last period of the Paleoz .... They have sutures that form 8 lobes and characteristically lack sculpture. The ventral lobe, as for the superfamily, is bifurcated.

Agathiceratidae
Agathiceratidae, as revised, makes up the goniatitid superfamily Agathiceratoidea. Agathiceratidae, which lived from the Upper Carboniferous (Pennsylvanian) to the Middle Permian, combine related genera with subdiscoidal to globular shells that have a small umbilicus and goniatitic sutures and are prominently longitudinally lirate. (Miller ''et al.'' 1960) The explanation for the Agathiceratidae is that for the Agathiceratoidea. Agathiceratidae may have its origin in ''Dombarites'' (Saunders ''et al.'' 1999) which has been removed to the Delepinoceratidae (Furnish ''et al.'' 2009). Delepinoceratidae is now one of two families that make up the Goniatitoidea. In current taxonomy (Furnish ''et al.'' 2009), Agathiceratidae contains '' Agathiceras'', '' Gaetanoceras'', '' Paragathiceras'', and '' Pericleites'' as compared to ''Dombarites'', '' Paracravenoceras'', ''Periclietes'', '' Proshumardites'', and ''Agathiceras'' in Saunders ''et al.'' (1999). ''Paracravenoceras'' is now ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Goniatites Bohemicus
''Goniatites bohemicus'' is a species of extinct cephalopods belonging to the family Goniatitidae, included in the superfamily Goniatitaceae. These slow-moving nektonic carnivores lived in the Mississippian epoch during the Carboniferous period in what is now Bohemia Bohemia ( ; cs, Čechy ; ; hsb, Čěska; szl, Czechy) is the westernmost and largest historical region of the Czech Republic.

Bavaria
Bavaria ( ; ), officially the Free State of Bavaria (german: Freistaat Bayern, link=no ), is a state in the south-east of Germany. With an area of , Bavaria is the largest German state by land area, comprising roughly a fifth of the total land area of Germany. With over 13 million inhabitants, it is second in population only to North Rhine-Westphalia, but due to its large size its population density is below the German average. Bavaria's main cities are Munich (its capital and largest city and also the third largest city in Germany), Nuremberg, and Augsburg. The history of Bavaria includes its earliest settlement by Iron Age Celtic tribes, followed by the conquests of the Roman Empire in the 1st century BC, when the territory was incorporated into the provinces of Raetia and Noricum. It became the Duchy of Bavaria (a stem duchy) in the 6th century AD following the collapse of the Western Roman Empire. It was later incorporated into the Holy Roman Empire, became an ind ...

Galerie De Paléontologie Et D'anatomie Comparée
The Gallery of Paleontology and Comparative Anatomy (in French, ''galerie de Paléontologie et d'Anatomie comparée'') is a part of the French National Museum of Natural History (''Muséum national d'histoire naturelle'', MNHN). It is situated in the '' Jardin des plantes'' in Paris near the Gare d'Austerlitz. The Gallery of Comparative Anatomy (occupying the ground floor), holds nearly a thousand skeletons and interprets their organization and classification. The Gallery of Paleontology (occupying the first and second floor) presents a famous collection of fossil vertebrates, fossil invertebrates and fossil plants. Among the most appreciated pieces by the public is worth mentioning a series of dinosaur skeleton casts (''Diplodocus'', ''Iguanodon'', ''Allosaurus'', ''Carnotaurus'', ''Tarbosaurus'', ''Unenlagia'', ''Dromaeosaurus'', '' Bambiraptor'') but also a ''Tyrannosaurus'' skull (cast of specimen AMNH 5027), an authentic skull of ''Triceratops'', an authentic ''Compsognathu ...

Ammonoidea
Ammonoids are a group of extinct marine mollusc animals in the subclass Ammonoidea of the class Cephalopoda. These molluscs, commonly referred to as ammonites, are more closely related to living coleoids (i.e., octopuses, squid and cuttlefish) than they are to shelled nautiloids such as the living ''Nautilus'' species. The earliest ammonites appeared during the Devonian, with the last species vanishing during the Cretaceous–Paleogene extinction event. Ammonites are excellent index fossils, and linking the rock layer in which a particular species or genus is found to specific geologic time periods is often possible. Their fossil shells usually take the form of planispirals, although some helically spiraled and nonspiraled forms (known as heteromorphs) have been found. The name "ammonite", from which the scientific term is derived, was inspired by the spiral shape of their fossilized shells, which somewhat resemble tightly coiled rams' horns. Pliny the Elder ( 79 AD nea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Goniatitida
Goniatids, informally goniatites, are Ammonoidea, ammonoid cephalopods that form the order Goniatitida, derived from the more primitive Agoniatitida during the Middle Devonian some 390 million years ago (around Eifelian stage). Goniatites (goniatitids) survived the Late Devonian extinction to flourish during the Carboniferous and Permian only to become Permian–Triassic extinction event, extinct at the end of the Permian some 139 million years later. Morphology All goniatites possessed an external shell, which is divided internally into chambers filled with gas giving it buoyancy during the life of the animal. An open chamber at the front of the shell provided living space for the goniatitid animal, with access to open water through a ventral siphuncle. The general morphology and habit of goniatites was probably similar to that of their later relatives the Ammonitida, ammonites, being free swimming and possessing a head with two well developed eyes and arms (or tentacles).
